dnsmasq: Update to version 2.86

Summary of upstream CHANGELOG:
* Handle DHCPREBIND requests in the DHCPv6 server code.
* Fix bug which caused dnsmasq to lose track of processes forked.
* Major rewrite of the DNS server and domain handling code.
* Revise resource handling for number of concurrent DNS queries.
* Improve efficiency of DNSSEC.
* Connection track mark based DNS query filtering.
* Allow smaller than 64 prefix lengths in synth-domain.
* Make domains generated by --synth-domain appear in replies
  when in authoritative mode.
* Ensure CAP_NET_ADMIN capability is available when
  conntrack is configured.
* When --dhcp-hostsfile --dhcp-optsfile and --addn-hosts are
  given a directory as argument, define the order in which
  files within that directory are read.
* Support some wildcard matching of input tags to --tag-if.
